Check Digit Verification of cas no

The CAS Registry Mumber 20157-14-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,1,5 and 7 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20157-14:
(7*2)+(6*0)+(5*1)+(4*5)+(3*7)+(2*1)+(1*4)=66
66 % 10 = 6
So 20157-14-6 is a valid CAS Registry Number.

The synthesis and structural characterization of furanyl-1,2,3-triazole Gold(I) and its application in synthesis of enones from propargylic esters and alcohols

Yao, Wei,Zhang, Yilin,Xu, Xiaqing,Yang, Yongchun,Zeng, Wei,Wang, Dawei

, (2019)

Furanyl-1,2,3-triazole gold(I) was designed, synthesized and characterized by X-ray crystallography, and was found to exhibit high catalytic activity for the synthesis of enones in good to high yields through a propargylic ester rearrangement and subsequent hydration. Notably, excellent E/Z selectivity was observed in these transformations. This catalyst was also effective in catalyzing the rearrangement of propargylic alcohols and hydration of alkynes. Compared to triazole acetyl gold(III) and other gold complexes, the furanyl-1,2,3-triazole gold(I) is able to promote these transformations smoothly at a low temperature with the E isomer of enones as the only product.

Triazole acetyl gold(III) catalyzed Meyer-Schuster rearrangement of propargyl alcohols

Yang, Yongchun,Shen, Yanan,Wang, Xiaoli,Zhang, Yao,Wang, Dawei,Shi, Xiaodong

supporting information, p. 2280 - 2282 (2016/05/10)

A new type triazole acetyl gold(III) was prepared and found to be an effective catalyst in Meyer-Schuster rearrangement of propargyl alcohols. The reactions proceeded well under much milder conditions to afford enones bearing a wide range of functional groups, thereby opening a new avenue for gold(III) catalysis. In addition, TriaAuCl2 catalyst was also effective on promotion of a-haloenones synthesis.
